New TunnelVision Attack Allows Hijacking of VPN Traffic via DHCP Manipulation

Researchers have detailed a Virtual Private Network VPN bypass technique dubbed TunnelVision that allows threat actors to snoop on victim's network traffic by just being on the same local network. The "decloaking" method has been assigned the CVE identifier CVE-2024-3661 CVSS score: 7.6. It impac...

K000139553: VPN TunnelVision vulnerability CVE-2024-3661

Security Advisory Description By design, the DHCP protocol does not authenticate messages, including for example the classless static route option 121. An attacker with the ability to send DHCP messages can manipulate routes to redirect VPN traffic, allowing the attacker to read, disrupt, or...

New Attack on VPNs

This attack has been feasible for over two decades: Researchers have devised an attack against nearly all virtual private network applications that forces them to send and receive some or all traffic outside of the encrypted tunnel designed to protect it from snooping or tampering. TunnelVision, ...
